In reply to bobpilgrem:
Thats a pretty big slice then, Sørlandet rock is best for Kristiansand/Mandal, for Setesdal I use the Setesdal guide by weninger and brunnert, which has text descriptions in english, but it also operates a weird E system I had never seen before that guide.
Further east I'd say Oslo & omegn guide and Drammen granit.
Telemark guide for telemark of course.
Not too sure what areas the latest Climb Norway encompasses, but the previous edition I have covered a few crags in the area you specified.
There is also a lot of stuff not in guide books but that is up on 27crags, so sometimes it's useful to check there and print out the topos.
